Flags of Vietnam: New Discoveries (This Vietnamese website published this page, reproduced from Francia Vexilla, containing scans from a long document in French which cites several other vexillological resources and contains numerous flag images. The flags described include national, sub-national, ethnic and religious flags, starting from pre-colonial era and until the end of Vietnam War.)
The five points of the star stand for the farmers, workers, intellectuals, youth and soldiers. Adopted 1955 (modified from 1945 flag). (Jos Poels, Prisma vlaggenboek, 1990) Mark Sensen, 19 September 1997
I did not see any reference to the date on which they turned on the actual pattern. Well, here it is: the current flag of Viet Nam was officially put into use by the then North Viet Nam on 30 November 1955. Pier Paolo Lugli, 10 October 1997
The adoption date given on FOTW is 30 September1955. On the other hand, Smith [smi82] gives date of "official hoisting 2 July 1976." This is explained, I guess so - the 1955 was adoption of the flag by Democratic Republic of Viet Nam (i.e. North Viet Nam), while in 1976 it was adopted by the united Socialist Republic of Viet Nam.

New Zealand's Prime Minister Helen Clark has just completed a brief state visit to Vietnam, prior to the APEC meeting in Thailand.
News footage here showed a motorcade with cars flying small NZ and Vietnamese flags. The Vietnamese flag definitely had the gold star displaced towards the hoist, I'd say about 2/5 of the way from hoist to fly, rather than centred as in the usual national flag. James Dignan, 19 October 2003
The protocol manual for the London 2012 Olympics (Flags and Anthems Manual London 2012) provides recommendations for national flag designs. Each NOC was sent an image of the flag, including the PMS shades, for their approval by LOCOG. Once this was obtained, LOCOG produced a 60 x 90 cm version of the flag for further approval. So, while these specs may not be the official, government, version of each flag, they are certainly what the NOC believed the flag to be.
For Vietnam: PMS 186 red, 116 yellow. The vertical flag is simply the horizontal version turned 90 degrees clockwise. Ian Sumner, 11 October 2012
Tonight, a user at Wikipedia pointed to specifications regarding the national flag of Viet Nam. On 10 October 2012, a guide (Huong dan, HD) was issued by the Ministry of Culture, Sports and Tourism (BVHTTDL) regarding not only the use of the national flag but also specifications for the size and placement of the star. According to the Guide, which can be read in Vietnamese at http://bvhttdl.gov.vn/vn/vb-qly-nn/1/1195/index.html, shows the star is centered on a flag that has a width to length ratio of 2x3. The star center to the top point has a radius of 1/5th of the length of the flag. A photo diagram, issued by the City of Da Nang at http://www.baodanang.vn/dataimages/201608/original/images1289003_Treo_co_1.jpg, shows the construction of the star on the flag.

Well found. This actually repeats decision (decree) No. 578 KHKY/QD on the "National Flag of the Socialist Republic of Vietnam" dated 30 December 1977 (effective 1 July 1978). You are quite properly correcting the construction details we have on FOTW – details which I should have noticed we had wrong. We show the star as being contained within a circle 2/3rds of flag width high, whereas the correct size of that circle is (as Zachary pointed out) 3/5ths - in other words 2-6-2 for the hoist and 15 for the fly.
